Well, one reason could be 'constant namespace pollution'. For example,
'Wine' (to be compatible with MS's headers) defines APIENTRY, CALLBACK
and WINAPI.

So, if you include Mesa's header files in Wine (what I do to support
OpenGL and to 'simulate' Direct3D), APIENTRY is modified by 'GL/gl.h'
(as it is #defined to nothing on non-Windows platforms).

Anyway, it is not such a big deal (I have a 'wine_gl.h' wrapper around
gl.h to reset the constants to the Wine-approved versions).
